Question

Most unsaturated fats are liquid at room temperature because a cis double bond:

Accepted Answer

C. Puts a kink that stops tight packing

1. A cis double bond changes the shape of the hydrocarbon chain.
2. It causes a bend, or kink, in the chain.
3. That bend prevents the fatty acids from packing tightly together.
4. Loosely packed chains stay liquid, which is why such fats are called oils.
